Extract C (paragraph 3) states that the Quantity Theory of Money 'postulates a direct, proportional relationship between the growth of the money supply and the general price level.'
Explain the term 'price level' and analyse how increases in the money supply of an economy may cause increases in its price level.

Central banking authorities around the world have long grappled with the lag between implementing monetary expansion and seeing its transmission into domestic demand. When central banks purchase sovereign bonds and financial assets, bank reserves swell. However, this does not immediately translate into consumer spending or private investment, as commercial banks may choose to hold excess reserves rather than lend them out during periods of heightened economic uncertainty.
Yet, when economic conditions stabilize, this massive liquidity buffer can quickly cascade into the wider purchasing streams. Rising rates of private lending boost the aggregate spending potential within the economy, leading to imbalances where aggregate demand outstrips short-term productive potential. Under these conditions, price growth accelerates.
Critics of prolonged quantitative easing argue that central banks often underestimate the eventual price impact of rapid monetary growth. Monetarists rely heavily on the Quantity Theory of Money. They view persistent inflation as a purely monetary phenomenon that occurs because the supply of money grows faster than the real output of goods and services.
This perspective is formalized in the Fisher equation of exchange. The theory postulates a direct, proportional relationship between the growth of the money supply and the general price level in the long run. Under this framework, excess nominal money balances lower market interest rates and depreciate the currency, triggering broad expansion in consumer demand and import prices, eventually pushing up the price level.
